'.Eatented May 21, 1907.

Application filed December 18, 1905. Renewed January 3, 1907. Serial No. 350,554.

To all whom it may concern:

and LARKIN A. HACKER, citizens of the United States, residing at Wash, county of Roger Mills, Territory of Oklahoma, and

Sprule, County of Knox, State of Kentucky, respectively, have invented new and useful Improvements in Cotton-Choppers, of which the following is a specification.

This invention is a cotton Chopper attachment for cultivators, and it consists in certain novel features of Construction hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of the attachment, a portion of the cultivator being shown in dotted lines to show the location and manner of securing the attachment thereto. Fig. 2 is a side elevation, and Fig. 3 an end view of the attachment.

Referring specifically to the drawings, denotes the wheels, 11 is the top frame, and 12 the tongue of the cultivator. The wheels are mounted on the usual arched axle 13 which supports the top frame, and the front end of said frame carries the draft-arch 14 to which the shovel-beams (not shown) are attached. The parts so far described are to be found on an ordinary Cultivator, and nothing is claimed with respect thereto.

4 The numeral 15 indicates an arched beam which is fastened to the top frame 11. At or about the middle of this beam are bolted or otherwise fastened spaced plates 16 between which the upper end 17 of a yoke-shaped frame 18 extends. This end of the frame 18 has a rack 19 which is engaged by a segmentgear 2() on a hand-lever 21 fulcrumed on a shaft 22 extending between the plates, whereby the frame 18 is raised and lowered. The hand-lever is provided with a spring latch 23 engaging with a rack 24 formed at the outer end of one of the plates 16.

The branch 25 of the frame 18 carries a hanger 26 having a bearing 27 in which one end of the chopper-shaft 28 is journaled and the branch 29 of the frame is formed with a bearing 30 for the opposite end of the chopper-shaft. The chopper knives or hoes 3 1 are mounted on the shaft 28. The hanger 26 has oppositely extending arms 32 which are slidably mounted on the depending stems 33 of the draft-arch 14.

The branch 29 of the frame 18 has a laterally extending arm 34 provided with a bear- Be it known that we, JAMEs H. CUBINE ing 35 for the drive-shaft 36 having a bevelgear 37 meshing with a bevel-gear 38 on the chopper-shaft 28. The drive-shaft is also supported in bearings 39 formed on a bracket 40 secured to the axle 13.

The drive-shaft has a sprocket 41 which is connected by a chain 42 with a wheel-driven sprocket 43. A suitable clutch 44 is provided for throwing the shaft into and out of gear. The drive-shaft is in two sections which are connected by universal joints 45 and two telescoping sections 46. This Construction forms a sliding joint in the driveshaft which is necessary to enable the frame 18 to be raised and lowered, because the bearing 35 moves with said frame and the bearings 39 are fixed to the axle.

In operation, the frame 18 is lowered by means of the gear 2O and rack 19, after which the hand-lever 21 is locked to the rack 24. Through the gearing herein described, the chopping knives or hoes 31 are revolved upon driving the cultivator over the Jrield in the usual manner, and by manipulating the handlever 21 the knives or hoes can be raised or lowered as desired.' To insure a free movement of the frame 18, the end 17 works against friction rollers 47 mounted between the plates 16.

We claim:

1. The combination with a wheeled frame, of a vertically adjustable chopper-shaft thereon, and gearing between the choppershaft and one of the wheels, said gearing having a flexible and telescoping section to per'- mit vertical movement of said shaft.

2. The Combination with a wheeled-frame, of a vertically adjustable chopper shaft thereon, and gearing between the choppershaft and one of the wheels, said gearing having a iiexible and longitudinally-extensible section to permit vertical movement of said shaft.

3. The combination with a wheeled-frame, of a vertically adjustable yoke-shaped. frame thereon carrying a revolving chopper-shaft, one of the branches of the last mentioned frame having a laterally-extending arm' provided with a bearing, a iiexible wheel-driven shaft, one end of which is carried by the wheeled-frame, and its other end in the aforesaid bearing, and gearing between the shafts.

4. The Combination with a wheeled-frame,

IOO

of an arched beam thereon, spaced plates eX- tending from said beam, a vertically adjustable yoke-shaped frame having its upper end formed with a rack and extending between the plates, one of the branches of the last mentioned frame having a laterally-extending arm provided with a bearing, a hand-lever having a segment-gear meshing with the rack to raise and lower the frame, a choppershaft j ournaled in the branches of the yokedshaped frame, a flexible shaft, one end of Which is carried by the Wheeled-frame and l the other end by the aforesaid bearing, and

gearing between the shafts.

In testimony whereof We have signed our 15 ,names to this specification in the presence of the subscribing Witnesses.
